APK A farmer buys 2.5 km of wire for fencing. He uses 850m in one field... …and 1.25km in another. How much wire does he have left?
NEW INFORMATION How do you work out the answer to a word problem? Read the question. Convert the units in the question so that all the units are the same, if possible. Decide what operation(s) to use. Write down the calculation(s) you are going to do. Use brackets if you need to. Work out the approximate answer. Decide how you will work out the calculation. Ask: Can I do it in my head? Do the calculation and interpret the answer. Include any units (e.g. km). Ask: Does the answer make sense?
In Interactive Notebook Year 5s and 6s: 1.Farmer Dom’s sheep are escaping out of his field, he needs to put a fence around it. a.
